If you’re looking for replacement garden cushions, getting the measurements right is the most important step. Even a few centimetres can make the difference between a perfect fit and cushions that look untidy or slide around every time you sit down.
In this guide, we’ll show you exactly how to measure your existing cushions or outdoor furniture to ensure your new cushions fit perfectly.
Why Accurate Measurements Matter
Garden furniture comes in hundreds of different shapes and sizes. Even furniture that looks identical can often have slightly different dimensions.
Correct measurements help you:
- Achieve a neat, professional look
- Improve comfort and support
- Prevent cushions from moving around
- Avoid costly mistakes and returns
- Get the most from custom-made cushions
What You’ll Need
Before you start measuring, grab:
- A tape measure
- A notebook or phone for notes
- A camera (optional but helpful)
For best results, use a flexible tape measure rather than a rigid ruler.
Measuring Seat Cushions
For seat cushions, you need three measurements:
Width
Measure from one side of the seat to the other.
📏 Example: 120 cm
Depth
Measure from the front edge of the seat to the back.
📏 Example: 60 cm
Thickness
Measure the height of the cushion from top to bottom.
📏 Example: 10 cm or 15 cm
Example size:
120 × 60 × 10 cm
Measuring Back Cushions
Back cushions are measured slightly differently.
Width
Measure across the cushion from side to side.
Height
Measure from the bottom to the top.
Thickness
Measure the depth of the cushion.
Example size:
60 × 40 × 10 cm
Measuring Rattan Furniture Cushions
If your old cushions are missing or worn out, measure the furniture itself.
For rattan furniture:
- Measure the internal seating area
- Measure between the arms
- Measure the usable depth
- Check if corners are rounded
Many rattan furniture sets have slight variations, even within the same collection.
Measuring Pallet Sofa Cushions
Pallet furniture is usually made from standard Euro pallets.
Common sizes include:
| Cushion Type | Typical Size |
|---|---|
| Seat Cushion | 120 × 80 cm |
| Seat Cushion | 120 × 60 cm |
| Back Cushion | 120 × 40 cm |
| Back Cushion | 60 × 40 cm |
Always measure your pallet seating before ordering, as DIY pallet furniture often varies.
Measuring Corner Sofa Cushions
For corner units, measure each section separately.
Record:
- Left section
- Corner section
- Right section
Do not assume both sides are identical.
A simple sketch with dimensions can help avoid confusion when ordering custom cushions.
Measuring Bench Cushions
For bench cushions, measure:
- Length
- Depth
- Desired thickness
Popular bench cushion depths are:
- 30 cm
- 35 cm
- 40 cm
- 45 cm
For window seats, measure the recess carefully and check whether the corners are square or rounded.
Should You Measure Existing Cushions or Furniture?
If your current cushions fit perfectly, measure the cushions.
If your cushions are old, sagging, misshapen or missing, measure the furniture instead.
Furniture measurements are usually the more reliable option for replacement cushions.
Common Measuring Mistakes
Measuring Curved Cushions Incorrectly
Always measure the widest points.
Forgetting the Thickness
Many customers remember length and width but forget thickness.
A 10 cm cushion feels very different from a 15 cm cushion.
Measuring from the Wrong Position
Measure the actual seating area, not the overall furniture frame.
Guessing
Never estimate measurements.
Even small errors can affect the final fit.

Final Thoughts
Taking accurate measurements only takes a few minutes, but it ensures your replacement cushions fit beautifully and provide the comfort you’re looking for.
When in doubt, measure twice, write everything down, and take a few photos before ordering. A little extra care at this stage can save a lot of time and frustration later.
